I want back the Myshuno bingo game that kept the party going, the surf machine from the Sims 2 console, dog houses and better pet beds, Always cars from the Sims 2, the hacky sack even though they were obsessed with it lol. Sims 2 Bon Voyage was one of my favorites like the vacations were everything. The Celebration pack especially the weddings OMG I miss those. The Shopping not the clothing but actual making a mall and walking into different stores. Actual hair salons.
Sims 3 I loved the burger places watching the games at the stadium, getting invited to parties and going to that person house at the party. My favorite will be Sims 3 University because it actually felt like a university but I also liked the Sims 2 sorority and frats. If we ever get another Sims game like a Sims 5 make the uni like Sims 4 how we pick our classes like we need 12 to graduate, but make it Sims 3 classes where we can actually interact and have Sims 2 sorority and frats pledge but also have the schools rivalry like Sims 4.
